The bigger they are, the harder they are to keep up, tear down, or reclaim. Urban Ghosts looks at very large abandoned buildings around the world, including a factory, a mansion, skyscraper housing, a church, and an office complex. Shown here is Chateau de Noisy in Belgium, which has been a home, a Nazi facility, and an orphanage before abandonment. See the inside of it at the post, as well as the other massive empty buildings.
